Abstract

PURPOSE:To realize favorable combustion state and prevent blowoff of the equipment by a method wherein an air supply tube communicating with a wind box is provided at the central part of a central burner so as to mix fuel gas with combustion air at the exclusive combustion of fuel gas jetted from a main burner. CONSTITUTION:The air supply tube 14 communicates with the wind box 6 and is open to an inner tube 8 by piercing through a scroll burner 3 as the main burner and the central burner 4. During the burning of combustion gas, the combustion air is supplied at the outer periphery of a nozzle part 3A from the wind box 6 and also supplied from the wind box 6 through the air supply tube 14 and the inner tube 8 by jetting out of an opening 8A toward an opening part 2 of a burner tile 1. In such a manner as mentioned above, because the combustion air supplied from the wind box 6 is jetted through the inner tube 8 locating at the central part of the central burner 4 out of the opening 8A, blast-furnace gas is sufficiently mixed with the combustion gas at its exclusive fuel combustion, resulting in ensuring the flame stabilizing and consequently preventing the blowoff liable to occur at the exclusive fuel combustion of blast-furnace gas.
